Ultrasonic flow meter for gas

The UF 322 G is a modern, accurate and reliable instrument for your gas flow measurements. The ergonomics of numeric and graphic screens makes easier the computation. In standard, this flow meter permits the storage of data and their transfer on PC (Excel) and integrates an oscilloscope function very useful to optimize the measurement and the diagnostic in difficult applications. The UF 322 G exists in several models from 1 to 6 chords (1 chord=1 pair of probes).

• UF 322 G-1 : 1 chord

• UF 322 G-2 : 2 chords

• UF 322 G-MC (6 chords) allows up to 6 speed integrations for the best accuracy even in difficult applications such as weak hydrolic conditions.

This ultrasonic flow meter measures the actual flowrate. It can be necessary to correct it with a PTZ corrector.

UF 322 G accept intrusive probes developped to resist to difficult pressure conditions. They can be directly installed on the pipe on charge without any break in the process (hot tapping) or on a spool for a better accuracy (multi chords system).

Option

Hazardous aera protection : EE x'm', EE x'me', EE x'md' suitable probe or EE x'ia' ultrasonic barrier.

Typical applications

* Pipe of natural gas transportation

* Ventilation

* Compressed air supply

* All pipes types. The highest diameter depends on the internal pressure :

Examples : max diameter of 300mm for atmospheric pressure. Max diameter of 1m for a 60 bars pressure and for velocity flow below 25m/s

* All pressures up to 100 bars.

Advantages

* Wide range of speeds measurements from some mm/s up to 20 m/s

* Typical accuracy with 1 chord : below 1% from 10 to 100% of the full scale measurement

* This accuracy can be improved with the number of chords

* No pressure drop

* No moving parts

* No servicing ( no recalibration)

* Bidirectional measurements

* Fast response time

Note: An RS485 output can be installed instead of the RS232 output
